Evolution of adiabatic availability and its depletion through irreversible processes
Adiabatic availability, a property, is defined as the largest work that can be done by a system in an adiabatic, constant mass and volume process; therefore it is a more inclusive concept that includes all other definitions of maximum work. Adiabatic availability of all systems at any state is larger than or equal to zero. Adiabatic availability of a system in thermodynamic equilibrium state is zero. Adiabatic availability of a composite made of a system and a reservoir is the same as the available energy (exergy) of the system with respect to the given reservoir. Change and destruction of adiabatic availability for different reversible and irreversible processes have been investigated and evaluated in this paper.
